The lever stops were put on thecars as a result of some serious accidents and it isknown that they have fulfilled their mission in severalinstances. 1106 Electric Railway Journal Vol 52, No. 25. DOUBLE SIDE FEED SPAN CONSTRUCTION Safety and Cost Determine Constructionof Side Feed Spans By G. H. McKelway Engineer of Distribution Brooklyn (N. Y.) Rapid Transit System THERE are two general types of side feed construc-tion. In one, which is by far the most usual, theside feed span is made of an insulated copper wire whichnot only carries the current from the feeder to thetrolley wire but also supports the latter. The ordinarymeans of support of this construction consists of a sidefeed yoke, the lips of which are hammered around theside feed span at a point where the insulation has beenremoved. With the other construction the function of the sidefeed is merely to carry the current to the trolley wireand it is relieved entirely of the weight of the latter,which is carried by a separate span of galvanized ironor steel wire installed beneath the insulated wire. Con-nections from the side feed span to the trolley wire aremade by taps hanging from the former and terminate inspecial sid
